To find the length of Addilyn’s bedroom, we can use the formula of a rectangle’s perimeter:

Perimeter = 2 • (Length + Width)

Since we are given the perimeter and width, we can plug in our values:

40 = 2 • (8 + Length)

Next, we simplify:

40 = 16 + (2 • Length)

Then, we subtract 16 from both sides:

40 - 16 = 16 - 16 + (2 • length)
24 = 2 • length

Finally, we can divide both sides by the coefficient (2) to find that:

24 / 2 = 12
2 / 2 = 1

Therefore, the length of Addilyn’s bedroom is 12 feet.
